Makelele was not the only Chelsea great to inspire Bakayoko, who rejected interest from Manchester United, to join the team where his hero Drogba earned the adoration of the Stamford Bridge faithful.
"He is definitely an example I wish to follow, be it the footballer or the person himself".
'Yes, Makelele helped me greatly.
